You are asking us to render a mfr guilty verdict based on a short grainy video. None of us can do that. Neither can we simply take your word on what she did or did not do. The only thing we can give is our OPINIONS based on what the short grainy video presents and the known fact that the vast majority of car accidents happen because of human error. Feel free to dislike my OPINION and disregard it entirely. It's not even worth the proverbial US$0.02.
If anything, what might be at fault is the fact that these new-fangled automatic transmission interfaces have very little standardization. Not too long ago, all auto trannies have very similar P-R-N-L gates. In fact, all our current cars still have them, including the Stinger (our G70 is 6MT). Say what you want about the clunky old shift levers being ugly, but they ALL work the same way. Any driver - regardless of experience level - can jump from one car to the next and operate the shifter fairly competently.
Now... it's digilever this, push button that, wonderwheel there, touch pad here... They all work differently and are often confusing as all get go. I myself am not surprised things like this does occasionally happen. I do remember a FB group post, of a Stinger driver that backed into another car, because of his reliance on Auto Hold. In his case, he was man enough to admit fault and that was commendable. However, it's tough to fight the human nature to blame somebody (or something) else when poop happens.
